This study develops a low-cost water filtration system using coconut shells and neem leaves to improve water quality in rural areas. The filtration process follows the model, confirming the neem leaf's efficiency as an economical and effective solution for wastewater treatment. The results indicate that coconut shell-based filtration significantly improves water quality, making it suitable for non-potable applications like irrigation, flushing, and groundwater recharge. At the same time, Neem leaf showed the best pollutant removal results. The findings highlight the effectiveness of natural materials in providing affordable, eco-friendly water treatment solutions, especially for rural areas, and highlight the potential of coconut shell as an environmentally friendly alternative to chemical coagulants as a practical solution for clean water. Finally, an experimental setup is established to test the filter's efficiency by measuring water quality parameters and flow rate before and after treatment as per the required test. Results indicate that the filtration process not only significantly upgraded water quality and extremely reduced contaminants, but also consistently guaranteed adherence to rigorously established water quality standards.
